Syrup dispensing-In that the tubular receiver L has an upwardly yielding and downwardly spring-pressed mouth-piece c' and an upwardly yielding valve y' normally Patented Nov. 1e, 1920.

held down against its seat k by a spring l,"v

to opening position when the mouth-piece impi'nges the bottle by Contactv of sa1d mouthiece with. a shoulder m on the valve stem, t'e tubular -reeei'ver in the present case is the same as that in my patent. 1n

thepresent case, thefdischarge outlet nof ent case has no upwardly seating valve. The upper end of the receiveris turned olf'` to form a nipple cluster o comprising three nipples, the ports p, p', p ofwhi'ch on the one hand and the passage g vof the tubular receiver on the Aother communicate with the valve chamber 1' of the valve casing which the turned off portion of the receiver forms. In the valve chamber is a rotary valve s formed with two opposite segmental ports t of such form that when the valve is Given quarter-turns the low through the nipple cluster will be alternately from port p to port p and from port p to passage g, and then from port p to passage g and from port p to port p. The valve and its chamber are tapering and the valve is held in place by a washer u and a nut o screwed on a threaded stem w of the valve. The valve has a projecting four-point ratchet or star wheel and a spring-pressed pawl y holds it in each of the quarter turn positions to which it is moved. The body of the re-l ceiver and an extension stem e thereof respectively slide in suitably fixed guides 2, 3. The receiver is made to 'rise and fall with the main slide by a friction-grip device consisting of an arm 4 aiiixed to a suitable projecting part 5 of the main slide and having a U-shaped extremity 6 receiving the body part of the receiver (Figs. 3, 4 and 8) and 'containing leather or other opposite friction grip elements 7 and a spring 8 to cause said elements tovexert clamping pressure on opposite faces of the receiver, the spring being backed by an adjusting screw 9. A screw 10, held in place by a nut l1, connects the extremities of the portion 6 of the arm 4 and a'ords a pivot for a springpressed pawl 12 whose outward movement under pressure of its spring is limited by a metal block 13 preferably interposed between spring 8 and the adjoining friction grip element 7. This pawl is adapted on each rise of the arm 4 with the main slide to click past the adjoining point of the star wheel m, and on. the ensuing downstroke to rotate the valve s a quarter turn. It will be understood that the slip grip which the arm 4 maintains on the receiver permits com ensation for bottles exceeding a certain heig t to occur, the receiver in such cases slipping relativelyupwardl in the arm 4; whenever such 'upward disp acement occurs, on the ensuing upstroke the receiver is reset downwardly b contact with some fixed part, as of its mout portion with the guide 3.

The central port p ofthe nipple cluster is connected with a suitable syrup source under pressure by the tube 14. The other l are connected with nally threaded extension has screwed into it the threaded adjusting spindle or screw 23 which, according as it is entered more or less into the extension 22, obviously more or less limits the range of movement of the piston. f i

It will be seen that the supply source, the parts 16, 17 and 15-20, the switching valve and the receiver form a uid delivery system in which the parts 16, 17 and 15-20 constitute a circuit-conductor interposed between the supply, source and receiver and the switch 4valve constitutes means for switching the pressure first in one direction and then in the other through the circuit conductorgthat the amount of Huid delivery on each lchange of position of the switchvalve is limited because the piston-throw is limited; and that such amount is rendered variable by adjusting screw 23 and consequently the throw of the piston. The pawl 12 invariably turns the valve s a quarterturn in each cycle of movement of the receiver with the main slide e., at the outset of each downstrike) so that, while delivery of syrup never occurs unless a bottle A is present to cause opening ofvalve j, pres sure is present in the receiver suilicient to4 produce a discharge of syrup on each downstroke. The amount discharged is always equal to the amount which the piston', fol-I lowing each switching movement of the valve s, displaces and this may be adjusted to a nicety by adjusting the screw 23.

Gasket control-While the gasket and its control means are herein described and shown in connection with an elementY (d) adapted to function as a compensating slide the same as inmy said patent and to have certain other arts shown and described in said patent ut not here relevant)v associated with it, it will be understood that the invention is not limited to the structure d having these qualifying elements.

The compensating slide or structure d has the filling (or sealing and filling) head 24 secured to its lower flanged end by cap screws 25., the same having a chamber 26 for the closure aixing appliance, a closure 1n- 'let l"27 and a closure supporting annular ledge 28'and a depending lip 29; 30 is the mouth-piece grooved to recelve the annulr dependlng lip 29 of he filling head, being carried b two'long vertical rods 31 which have slidmgbearings in the (tubular) cap screws andare equipped at their upper ends with nuts or equivalent abutments 32, being arranged one at each side of the structure d and projecting above the same and through lateral ears`33 thereon. The mouthpiece supports, interposed between itself and the ledge 28, the annular elastic gasket 34. The structure 30-31 forms in effect a stirru to su port and, in co-action with the llling hea exert compression on the Gasket. Screwed fast into the ears 33 are the upwardly projecting posts 35, penetrated by the rods 31. Screwed fast onto the upper end of each post is a fixed nut or cam device 36 formed with regularly spaced downward projections having their lower faces 37 horizontal and their corresponding side faces 38 beveled ina manner equivalentto a screw thread or cam face. A movable nut or cam device is associatedwith each nut or cam device 36 and constructed as follows: 39 is a cylinder into the lower end of which is screwed fast a nut or cam member 40 (Fig. 16), which is the complement of the nut or cam device 36l (in that it has cam projections 41 which are reverse counterparts of those of the cam device 36) and is journaled on the post 35 below the same, and into the upper end of which cylinder is screwed fast a plug 42. A powerful spiral spring 43 is housed in the cylinder 39 and interposed between the cam device 36 and an anti-'friction bearing-designated as a .whole by 44- which bears against the plug 42 and the lower plate 44 of which directly assumes the thrust of the spring. Secured fast on the top of each cylinder 39 by set-screws 45 is a cap 45 in which on a studA 46 is fulcrumed a chock consisting of a lever 47 providedwith a handle, as shown, and with a bearing 47', having a lateral entrance or opening 47, for the tubular chock-proper 48 swiveled in such bearing and having the vslot-and-pin connection 49 therewith, said chock-proper having the longitudinal slot 5() adapted to register with the entrance 47" to said bearing, it being understood that 'such slot and said entrance permit the chock to be moved clear of rod 31 into and out of the position where the chock-proper underlies the abutment 32 on the rod and receives the latter in its bore (Figs. 13 and 20). When in this position the chock proper rests upon a tubular thrust-piece 48', vin turn resting on the plate 44', and is thus adapted to transmit the Aupward pressure of the spring directly to the stirrup. The cam de- `at which time the gasket will be in a state yof considerably reduced compression. It is vices 3 9-40-42 are adapted to be turned clockwise, 'as seen in plan; to bring the horizontal facesthereof against those of the cam devices 36 and anti-clockwise to bring the cam projections of the two sets of camdevicesinto mesh 4with each other. In the first of these positions (Fig. 13) the cam devices 39-40-42 have been cammed down by the inclined faces of the cam projections, consequently lowering the mouth-piece 30 and reducing the pressure on the gasket, which relaxes and expands interiorly; in the second position the cam devices 39-40-42 and consequently the mouth-piece are full up, the gasket being held contracted to its minimum interior diameter. The chocksl form portions of the cam devices, interposed between the caps 45 thereof and the abutments 32, 'which are withdrawable, by swinging them on their fulcra to the dotted line position shown in Fig. 20, so that the stirrup may be allowed to fall to the position shown in Fig. 14 thus to afford clear access to the gasket containing chamber, as for substituting for a worn gasket a new one; this operation of withdrawing the chocks so as to lower the stirrup is of course most readily effected when the cam devices 39-40-42 occupy the first position above mentioned,-

preferable that when the cam devices 39-40-42 are in the said rst position the gasket be under some compression so that the downward pressure it thus exerts on the stirrup will produce suiiicient friction between the abutments 32 and the chocksproper to/prevent the latter, which are manually turned in their bearings 47' to block the entrances 47 thereto, from working out from under the abutments. It will be understood that thel slot-and-pin connection 49 limits the rotary movement of the chocksproper, so that it requires but a slight man! ual movement thereof to bring their slots into registry with the entrances 47". Adj ustment of the degree of compression of the gasket may be obviously effected by adjusting the abutment-forming nuts 32.

For effecting automatic expansion and 115 contraction of the gasket in the filling of the containers, and in particular where, as herein shown, such expansion and contraction are to -be coordinated with the operations of a machine like that set forth in my said Letters Patent, the following mechanism may be provided: crank 51 embraces the basal portion of each cam device 39-40*42 and is secured fast thereto by a set-screw 52 which holds a tangential plug 125 53 binding the cylinder 39 against the cam member 40 (Fig.4 15). The pair of cranks are connected bya link 54 and one of the cranks has a roller 55 vengaged in.a slot 56 (somewhat wider than the roller to allow some lost motion) in a crank 57 on shaft g. When the main slide is fully elevated the shaft g will stand' at its limit of clockwise movement (see my patent aforesaid, page', line et seg.) and the pair of rotatable cam 'devices at their limits of anti-clockwise movement, as seen in plan. (The main slide and shaft g are shown--Figs 1 and Qf-in the positions where the former has started to rise and the latter, having performed its working stroke so far as the control of the gasket is concerned-to wit, to release the gasket-has started its clockwise movement.) At that time the cam-projections of of the rotatable and fixed cam devices will therefore be meshing with each other, where- 'fore the springs 43 hold the latter and hence the stirrup at their full upward limits, compressing the gasket into the contracted lform in which it is to be forced down over the bottle mouth. When on descent of the main slide, as in my said patent, the bottle mouth having entered the contracted gasket and thereupon, been filled and the closure having been introduced over the bottle mouth and a hermetic seal formed between them, the last part of the descending move- `ment of the main slide for closure affixing occurs, crank 57 in now moving anti-clockwise brings the left` side of its slot 56 against roller 55, so that the rotatable cam devices are rotated clockwise to the position where the horizontal faces of vthe cam-projections abut each other, involving compression of the springs and relaxation of the gasket, so 'that it can slip freely downwardly over the bottle neck. In the return or clockwise movement of the main slide, slot 56 permits somelost motion before the crank 57 at the right side of its slot engages and 'resets gasket until the bottle has been ejectedl from the filling head), whereupon it rotates the rotatable cam devices now anti-clockwise, thus permitting the springs again to raise the stirrup and so contract the gasket.
